BURR-WHEEL FOR KNITTING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 424,314, dated March25, 1890.

Application filed June 20, 18%9.

To all whom it may concern:

Be it known that I, PETER S. KINsEY, of Newark, in the county of Essexand State of New Jersey, have invented a certain new and usefulImprovementinBurrWVheels for Knitting-Machines, of which the followingis a specification.

My invention relates to bu rr-wheels for knitting-machines adapted toproduce figured or [0 pattern knitting.

Burr-wheels of the kind referred to have been previously made whichcomprised blades set obliquely on the periphery of the burrwheel hub,and so secured upon the hub that spaces are left between the blades.After the blades have been secured upon the hub certain of them have hadthe spaces between them filled up by means of solder, lead, or similarsoft metal run in in a molten state, where it becomes a fixture andsecures together the blades between which it is run. Burr-wheels thusconstructed, when once the spaces between the blades have been filled inby the soft metal, cannot be used for any pattern other than that forwhich they were originally constructed, for which reason it has beennecessary to construct separate burr- Wheels for each separate patternwhich was desired. By my improvement I obviate this 0 difficulty, for Iso construct certain of the burr-wheel blades that their positions maybe changed in any desired manner to produce any given pattern, thusmaking it possible to produce a great number of patterns with the sameburr-wheel.

The invention consists in making certain of the blades of which aburr-wheel is composed with enlargements upon one side thereof, whichenlargements form part of or are integral with the blades upon whichthey are formed, and which enlargements are of such thickness that whenthe blades are arranged upon the burr-wheel hub the enlargements willsubstantially fill the spaces between the blades upon which they areformed and the next adjacent blades upon one side. It is of course to beunderstood that the object of filling certain of the spacesbetween theburrwheel blades is that when the knittingnna chine cylinder containingthe needles is re Serial N0.3l5,001. (No model.)

volving such of the needles as come in contact with the closed spaces ofthe burr-wheel will have their barbs presssd in, so that a stitch willbe cast off. Such of the needles, on the' contrary, as come opposite theopen spaces between the burr-wheel blades will mesh into such spaceswithout pressing in the barbs, and from such needles the stitches willnot be cast off.

In the accompanying drawings, Figure 1 is a view showing a burr-wheelembodying my improvement in perspective, together with a portion of aknitting-machine cylinder. Fig.

2 is a plan or top view of the burr-wheel. Fig. 3 is an edge view of thesame. Fig. 4 1s a transverse section thereof, taken on the line 00, Fig.3. Fig. 5 is a plan or top View of a burr-wheelembodyin g myimprovement,showing a diiferent arrangement of the burr-Wheel blades than is shownin Fig. 2. Fig. 6 is an edge view of the burr-wheel shown in Fig. 5.Fig. 7 is a side View of one of the thickened blades with the face uponwhich the thickened portion is formed in front. Fig. 8 1s a transversesection of the blade shown in Fig. 7, taken in the line m Fig. 7 Fi 9 isa side View of a burr-wheel blade of ordinary construction and ofuniform thickness. Fig. 10

is a transverse section of the same, taken on the line 00 Fig. 9. Fig.11 is a perspective of So the burr-hub with the blades removed.

Similar letters of reference designate corresponding parts in all thefigures.

I-I designates the hub of the burr-wheel, which may be made, in theusual manner,with obliquely-arranged slits or slots 3 in its peripheralface.

B designates blades of ordinary construction, or, in other words, whichare of uniform thickness throughout.

B designates blades having secured to them or formed integral therewithupon one of their sides enlargements e, which increase their thickness,and which extend approximately to the outer edges of said blades, as at6 Both the blades B and B are to be inserted in the slots 8 and when soinserted will extend obliquely to the axis of the huh.

I have shown a convenient method for securing the blades 13 and B in thehub, con- ICO sisting in providing the upper rearward edges of saidblades with locking-bevels l), which engage a recess 6 formed upon theupper side of the hub. In order to lock the blades in the hub, I haveshown a plate P, which plate is provided with a central aperture Q, sothat it may be passed downwardly over a sleeve T upon the burr-wheelhub. \Vhen in use, the sleeve T is placed upon a supporting arm orbracket A, mounted in a standard S, extendin g upwardly from a table orsupport T The securing-plate P is adapted to clamp by its outer rim pthe inner edges of the blades B B and hold them in position. In order tosecure the plate P, I have shown a nut n, engaging the screw-threadedupper portion of the sleeve T. I have also shown a washer VV,haVing acentral opening 0 and arranged between the nut n and the plate P. Whenthe nut n is screwed down, it will secure the plate P and preventdisplacement of the blades 13 and B 0 designates a part of aknitting-machine cylinder,N the needles thereof, and a web of knittedfabric.

With the parts thus made and arranged, when the blades B and B areinserted with their inner-edges within the slits of the hub and aresecured therein, such of the blades B as are employed will close up thespaces between them and the adjacent blades B on those sides of theblades B which are provided with the enlargements 6. Thus series of thespaces between the blades may be closed and such series produced inalternating sequence in the wheel-rim to act upon the needle-barbs topress them in at regular intervals and at intermediate intervals omit topress them in, so that in the one instance the stitches will be cast offand in the other they will not be. By the use of the blades 13' and B soconstructed they may be arranged in the burr-wheel to produce a greatvariety of patterns by their grouping and relative arrangement therein.

That I claim as my invention, and desire to secure by Letters Patent, is

The combination, with a hub having obliquely-extended slots upon itsperiphery and provided with a recess in its upper face, of blades madeto enter said peripheral slots and said recess in the hub top, certainof said blades each having thickened portions or enlargements upon oneof its sides, and a cap constructed to be passed down over the hub andupper ends of the blades and secured to the hub, substantially in themanner as and for the purposes set forth.
